SHIM COMPANY, INC., 01? LONG ISLAND YORK OF QUEENS VILLAGE, NEW YORK,ASSIGNOR TO LAMINATED CITY, NEW YORK, A CORPORATION OF NEW SHIM. ANDsHIM PACK Application filed August 27, 1925. Serial No. 52,837.

This invention relates to an improvement in shims for motor bearings andother uses, and to the methods of producing, marketing and using thesame.

It is an object of the invention to provide a shim pack and method ofmarketing the same which will facilitate the use of the shims, preventloss and damage to the individual shim and provide shims of varyingthickness to meet various needs.

Another object of the invention is to provide a pack comprising a largenumber of shim laminations, detachably secured together so as to permitremoval of any desired number of laminations as one unit, withoutseparating or loosening any other of the laminations from the pack.

Various other objects and advantages will appear from the followingdescription of my invention, which, taken with the accompanyingdrawings, discloses a preferred form of embodiment thereof.

In the drawings:

Fig. 1 is a side view of my improved shim pack.

Fig. 2 is an end view thereof.

Fig. 3 is a plan view.

Fig. 4 is a View showing how any desired number of individual shimlaminations may be removed without separating either the individuallaminations removed or those remaining in the pack.

Fig. 5 is an end view of a modified form of the invention.

In the manufacture and marketing of shims of the type contemplated bythis invention, it has heretofore been customary to provide a pluralityof thin laminations, .001 to .010 thick or thicker, which are formed tothe general shape of the bearing and provided with a hole or recess forreceiving the bolt which secures the parts of the bearing together, andto market these shims or laminations in bunches of 1000 or more eitherloose or secured together by means of one or more wires passed throughthelloolt hole and around the outside of the pac These bunches orpackages are shipped to the motor or engine maker where the shims ofproper thickness are assembled between the halves of the motor or otherbearing. In the assembly room the wrapping is removed or the tie wiresare cut so as to get access to the individual laminations, and theselaminations being of very thin metal which has a very pronouncedtendency to curl at the edges, often become scattered, drop on the floorand are lost or damaged, or curl so as to make the handling and countingof the same very difficult, and retard the assembly of the bearing. Toovercome these difliculties, the laminations are often formed into shimsof standard thickness and permanently secured together by means ofsolder between their adjacent faces or along the edges or by othermeans. This, however, greatly increases the cost of each shim thelaminations of which are thus separately assembled and secured together,and where a shim which is not of standard size or where only onelamination is desired, the standard size 7 shim must be reduced inthickness'before it can be applied to the bearing, thus increasing theassembly costs. 0

My invention admirably overcomes these objections and disadvantages, andat the same time provides a convenient supply of shims of eitherstandard or odd sizes.

In the manufacture of my improved shim or shim pack, I provide aplurality of individual laminations 1, preferably in lots of a thousandor more, and assemble them into a pack 2 with the edges thereof and thehole 3 for the bearing bolt in alignment. I then clamp or hold this packin assembled or stacked relation, paint an acid or soldering flux alongone edge thereof, preferably the back 4, and dip this edge into a moltensolder bath, permitting the solder to penetrate a In this condition thepack may be shipped intact and when desired individual or a plurality oflaminations may be removed without scattering or disturbing the otherlamiing shims, and solder on only a small portion of the edge surfaceadapted to retain the shim laminae together while permitting readyremoval of any quantity of laminae, certain of said being irregularlyformed to facilitate counting thereof.

In testimony whereof I have affixed my signature to this specification.

nations in the pack, and various other advantages are realized.

Instead of having to pick up and count 2. bunch of individuallaminations, many of which will be curled along the edges, and fiattenand hold them together until inserted in the bearing, the person doingthe assembly work can count oif the desired number of shims 6, asillustratedrin Fig. 4, pull then away from the pack 2 by breaking thesolder along the back, without separating other shims from the pack, andwithout separating the individual shims in the bunch 6, and with thelaminat-ions in the bunch 6 held together by the solder 5 along oneedge, he can easily and quickly insert the shim as a unit in thebearings.

Since the shims or laminations 1 are secured together along one edgelike the leaves of a book, they may be very esaily counted in a mannersimilar to thumbing through the leaves of a book.

The counting of the laminations may be facilitated by cutting away acorner of every fifth or so shim, as indicated at 9 in Fig. 2 or byforming every fifth or so shim with a bump or irregularity 10, asindicated in Fig. 3.

Fig. 5 shows a pack 7 consisting of a plurality of laminations l securedtogether along one corner 8 and along the back 4. This leaves one cornerof the shims free for counting and holds'the shims in'such a way as togreatly reduce curling thereof. Instead of soldering, the shims may besecured fogether by brazing, spot welding, or the ike.

It will be readily seen that my invention provides a new and economicalway of marketing and assembling shims which reduces the loss thereof andpermits great economy in the time of handling the same.

Various modifications and changes may be made in my invention, and partsthereoi may be used without others without departing from the spirit ofthe invention or the scope of the appended claim.

I claim:

As an article of manufacture, a shim pack solely comprising a pluralityof identical shim laminae sufiicient for a plurality of bear-
